Abstract: 

An experiment was conducted to study the “influence of plant growth regulators on strawberry cv. Chandler under Odisha condition” during 2013-2014. The experiment was laid out in a randomized block design with ten treatments considering of control (water), GA3 (25, 50 and 100 ppm), NAA (25, 50 and 100 ppm) and IAA (25, 50 and 100 ppm) and replicated thrice. Observations were recorded on different vegetative characters like plant height (cm), plant spread (cm), petiole length (cm), leaves per plant, runners per plant, different reproductive characters like days taken to first flower, days taken to fruit bud development, number of flowers per plant, number of fruits per plant and different fruit characters like Length: diameter ratio, Specific gravity, Juice (%), TSS (°Brix), Ascorbic acid (mg/100g), acidity. Treatment GA3 @ 100 ppm gave the best results in terms of vegetative growth and runner production. Different yield attributing characters were found better in NAA@100 ppm whereas Physico-chemical characteristics were superior in the treatment 50 ppm NAA. But ascorbic acid content and acidity percentage were higher in GA3 50 ppm.
